płyta : UN62 rev1.02
CPU : Intel Celeron 2957U

Witam
Posiadam Vivomini UN62 rev1.02

Port HDMI sprawny wizualnie, sprawdzałem i są przejścia do płyty głównej,
niestety nie wyświetla obrazu. Na Display Port obraz jest, ale po
załadowaniu Windowsa trzeba odpiąć i podpiąć kabel wtedy się obraz pojawia,
jeśli tego nie zrobię to jest czarny obraz

Dodam że wszystkie napięcia +3.3v oraz 5v są obecne

Co sprawdzić, gdzie szukać problemu.

Pozdrawiam

Na początek bym sprawdził ustawienia w bios i opcje pod systemem w ustawieniach grafiki na jaki port jest podawany sygnał. Sterowniki wszystkie są ?

Sterowniki wszystkie są, jak podepne pod HDMI to monitor się wzbudzi na sekundę, czyli wykrywa podłączenie ale obrazu nie daje. Na układzie od zarządzania HDMI występują wszystkie napięcia.

Set your multimeter to the diode test mode and measure the voltage drops to ground on pins 1, 3, 4, 6, 7, 9, 10, 12, 13, 15, 16, 18, 19 of HDMI connector with the red (positive) probe connected to the ground.

It's best to use a HDMI test board:

The voltage translator chip ASM1442 is very likely damaged. Remove it from the board and remeasure the voltage drops from post #5.
